Road pavement
serviceability is primarily governed by the type of vehicles anticipated to use
the facility. Along with the size of traffic loads, climatic conditions affect
the behavior of the materials in a pavement structure. The relative strength
loss in a layer due to its drainage characteristics and the total time it is
exposed to near-saturation moisture conditions is represented by drainage
coefficients. There is a need for computerized methodologies for thickness
design of flexible asphalt pavements (granular base course) for a wide variety
of pavement uses providing users the capability to conduct structural analysis
of special pavement structures. An algorithm for a computer-based procedure
towards the calculation of the layer thickness of flexible pavements has been
developed. The design equation used is that described by the American
Association of State Highway and Transportation Officials. The present work
deals with the effect of drainage on the total thickness of the structure as it
directly influences the cost of large infrastructure projects like roads. The
output of different cases solved is presented in table and schematic form.
Changes in technology related to pavement design and construction practices
will necessitate revisions to currently used computing techniques. Improvements
in computing times which will affect the cost of computerized methods available
to engineers are to be suggested in the near future. Empirically supported
pavement designs used nowadays in Greece require modifications based on
regional experience and on a better assessment of the drainage conditions
prevailing in each area crossed by a roadway project. Since design
considerations constantly change, it is obligatory to shift towards more
sophisticated design methods.
